  1. I am presuming that is available ram the rest is allocated to system resources.
  2. maybe its because of a 32-bit operating system that it shows less? but even then it should be like 3.25gb i think.
  3. Your GPU memory counts towards the grand total of 4 gigs for your 32 bit OS. Since it's a little more than one gig missing out of the total chunk, I have to ask if you have an integrated GPU as well as your Nvidia card? If you do, turn it off. If not, there's not much you can do. I think you should move to a 64 bit OS.
  4. If i move to a 64-bit OS, most of my hardware does not work on it. Any other way to correct this?
